Triangle Classification: Is This an Acute-Angled Triangle?

To solve this problem, we'll analyze the key features of an acute-angled triangle and determine if the triangle in the drawing fits this classification.

Definition Review: An acute-angled triangle is a triangle where all interior angles are less than $90^\circ$. This implies examining the geometric structure to ensure no angles exceed or equal $90^\circ$.

Steps for Verification:

• Analyze whether changes in angles can lead to right or obtuse angles.
• Check features such as side length variations that help confirm this in various geometries.
• Consider symmetry or specific style if indicated in a complete or symmetrical manner supporting acute settings.

Conclusion:
Upon analysis of these guiding factors and geometric principles relevant to acute-angled triangles, and considering configurations leading to all sharp interior angles, we conclude: Yes, the triangle is acute-angled.
